Re: [Linaro-mm-sig] [RFC 1/2] dma-buf: Introduce dma buffer sharing mechanism

+struct dma_buf_attachment *dma_buf_attach(struct dma_buf *dmabuf,

• struct device *dev)

+{

• struct dma_buf_attachment *attach;
• int ret;
• BUG_ON(!dmabuf || !dev);
• mutex_lock(&dmabuf->lock);
• attach = kzalloc(sizeof(struct dma_buf_attachment), GFP_KERNEL);
• if (attach == NULL)
• goto err_alloc;
• attach->dev = dev;
• if (dmabuf->ops->attach) {
• ret = dmabuf->ops->attach(dmabuf, dev, attach);
• if (!ret)
• goto err_attach;
• }
• list_add(&attach->node, &dmabuf->attachments);

I would assume at some point this needed at attach->dmabuf = dmabuf; added.
